Okay, i'm writing here, because GM in game told me that its best place for it, so thats what happened.
Friend of mine sent me via mailbox Rare Fortune Shoulders for Shadow Warrior with COD for 150g, but when i checked on my Shadow Warrior that i already have that piece of set i wanted to send it back, but i simply miss clicked on Report Spam button, and whole msg disappeared from my mailbox.

I'm using zMailMod and its pretty easy to miss click between X and Report Spam msg, and that's what happened this time.

All i'm asking is can that mailmsg come back to author (with contain ofc) ?

Character from which mailbox it was reported: Xergon
Author of mail with item: Susieq

This is not the right topic for it, this is when you played in a zone and failed to get rewards fro the zone.
And it sounds like you are reporting something working exactly as intended. Report spam deletes the email and reports the message and title to the GM team.

Awesome! Thanks for help and understanding...

So my advice, to avoid these mistakes in future is to make additional window, which pops up after user click on button "Report Spam" that needs confirmation and informs what about to happen.

Summary: No bag roll and no xp/inf reward for zone flip. You can clearly see my rewards from bo captures/defense (left) and my damage on lord (right). I had been in the zone ~30 minutes. Interestingly, I also didnt receive credit for capturing Kazad Dammaz Keep either.
